I believe the Oxygen Advantage really did help deal with altitude better on my trek to Everest base camp. As we ascended both Chris and I could feel the lack of oxygen but using the nasal breathing techniques you taught us, we seemed to adjust faster than the rest of the group. There were also several members suffering with symptoms of AMS (Acute Mountain Sickness) we didn’t have any problems. I was also very surprised that my SPO2 levels, as mine barely dropped below 90. The other benefit now I am back home , I sleeping like a baby and no longer snoring!"
